Description:
A vulnerability has been reported in rsync, which can be exploited by malicious users to cause a DoS (Denial of Service) and potentially compromise a vulnerable system.
The vulnerability is caused due to an integer overflow error in the "receive_xattr()" function within the xattrs.diff patch. This can be exploited to cause a buffer overflow and may allow arbitrary code execution via specially crafted extended attributes.
Successful exploitation requires that the "xattrs.diff" patch has been applied.
The vulnerability has been reported in version 2.6.7. Prior versions may also be affected.
Solution:
Update to version 2.6.8.
